United States Patent Office 2,697,298 Patented Dec. 21, 1954 BIRD CALLWHISTLE John H. Bacon, Wellesley, Mass. Application August 20, 1948,Serial No. 45,317 26 Claims. (Cl. 46-44) The present invention relatesto a whistle and especially to one having a resonating pipe which may bevaried in frequency and to means for producing a note which may bemodulated at a low frequency beat, the frequency of which may be made tovary.

The whistle of the present musical instrument, a toy, or to imitatevarious nature calls of birds and other creatures. The whistle of thepresent invention is operated by an air jet, supplied by a person or inlarge embodiments by mechanical means. The air stream is directedagainst the mouth of the whistle at such an angle that a sound vibrationresults whose frequency is predetermined by the length of the resonantair column in the pipe of the whistle. To this extent the frequency isestablished in the same manner as in an organ pipe. In addition to thishowever a deflecting plate supported by means of a freely vibratingspring has its end positioned in the mouth of the whistle in such amanner and at such an angle as to cause a periodic interruption of theair jet against the lip of the mouth to produce the desired beat noteeffect or what may perhaps be more commonly called a modulation orwarbling of the note of the whistle.

In the present invention the warbling or modulation does not affect thewhistle note itself. Provision however is made in the present inventionboth for changing the frequency of the note and also varying frequencyof the warble or modulation. The warble may also be periodicallyomitted. As a result of these provisions which form a part of thepresent invention, the whistle may be used to simulate a great varietyof bird calls and is, therefore, of considerable interest to those whostudy birds and desire a simple device for imitating their calls. Thewhistle of the present invention will produce musical sound effectswhich are sometimes lacking in orchestral renditions because of lack ofinstruments able to produce the desired eifects.

In addition to these uses the present invention will furnish a compactlow frequency standard of a standard note and also of a beat note byproper calibration respectively of the air column in the pipe or tube ofthe device and the calibration of the vibrating spring.

As a toy the device may have an animated figurine of a bird whose beakand eyes may move with the operation of the whistle. The device, whethertoy or not, may be .made of any suitable material such as a metal orplastic and it may be cast or molded assembled together.

Without further describing the merits and advantages of the presentinvention, the invention will be described in various modifications asillustrated in the drawings, in which:

In the arrangement shown in Figure 1, the device comprises a mouth piece1, a pipe 2 and a slidable plunger or piston. The mouth piece may bemade of any suitable material such as metal or plastic and can bereadily made by injection molding of a suitable plastic molding materialsuch as cellulose acetate or other common molding powder used for thatpurpose. The mouth piece is provided with an air passage 4 which has adecreasing tapering passage directing a sharp narrow air stream at thelip 5 of the mouth 6. The direction of the air passage 4 and the shapeand position of the lip 5 of the month are quite critical and should beso constructed and positioned that the air stream will be split by themouth lip 5. A spring 7 with a fairly long arm 8 carries at one end adeflecting plate 9 which reaches down into the air stream and willvibrate when the stream hits it. The spring 7 has a forwardly bentsection 10 and a rearwardly bent section 11 aligned with the arm 8 butnot closely parallel to it. The section 11 of the spring serves as aclamping area by means of which the spring is held in place on the pipe2. For this purpose the pipe 2 which may have a round cross section 12(see Figure 4) has a flat outer top section 13 with a recessed section14, in which the spring section 11 is positioned. A clamping collar 15is slipped on the back of the tube from the end, over an increasinglyenlarged section 16 of the tube, the clamping collar or band beingsimilar in shape to the section 16 of the tube so that the clamping bandwill bind the spring section 11 tightly to the tube as the band isforced forward on the tube or pipe. The section of the spring emergingfrom the clamping section 10 is, as has been explained before, bentbackwards in the section 10 to provide a backward section 17, which whenpressed downward by the finger will raise the deflecting plate 9 out ofthe mouth of the whistle. The spring 7 may be provided in the section 3with a slidable weight 18 which, by moving along the section 8 of thespring will vary the frequency of the spring and therefore the frequencyof the beat or warble. The frequency of the beat in the tube may bevaried by the plunger or piston 30 which may be a round pencil of theappropriate size or any type plunger, preferably with a fiat end. Theplunger may be held secured in the pipe or tube for carrying purposes bymeans of a band 19 of rubber or the like slipped over the slotted end 20of the tube to hold the plunger in place. The pipe 2 may also beprovided with side extending flanges 21 and 22.

These flanges may extend from the mouth piece back to the end of thespring at 17. The front sections 23 of the flanges may be attached tothe mouth piece 1, while the rear portions 24 may be attached to theoutside of the pipe 2. The flanges in the sections 24 have alongitudinal slot as indicated at 25 to permit the clamping band 15 tobe slid over the end of the pipe.

Referring again to the mouth piece section it will be noted from Figure2 that the cross section of the passage 4 is arcuate and formed betweenthe arcuate block which y be dasapart of t e outh p ece. and the topportion 27 of the top wall. The mouth piece is provided with a shoulder,28 which is made to fit and receive the end 29 of the pipe 2withpreferably a forced fit not to be removed after it is onceassembled, The ,pipe 2 may be made of a transparent plastic material andcalibrated with graduations 30 which maybe in ,octayes or portions ofoctavesto provide a'frequency calibration for the end of the'pencil orplunger30 in .its position in and out of the pipe. The whistle may becarried in a'pocket by a clasp or clip 31 attachedto the mouth piecejust below the front end. e

As indicated in Figures l through 4, the whistle may, for the most part,be rounded in form with a top flat section towards the end to fit theshape of a flat spring. ,I-Iowever,,the shapeof the spring at theclamping position may also be made arcuate and in this case the clamp-..ing band will be made circular and the whole pipe can be made in thesame form with the use of a forced fit ciamping bandor a slight taper inthe end section of the pipe on the external surface so that the springcan be held .,tightly in its position. This arrangement is shown inFigure 11 where the section of the pipe is indicated .at 32, .thearcuate clamping section of the spring at 33 and the clamping band at34. The springmay be gradually flattened out with the first reverse bandsection 35 of a slightly less curvature than the section 33 and the topsec- -,tion 36 of the spring completely flat. The band 34 may beprovided with a slight recess to receive the spring secxtion 33 and itwill be notedthatall of the circular sections are concentric with acentral axis of the pipe.

Intheoperation of the modification shown in Figures --1 to 4 theoperatorblows into the whistle through the -mouthpiece 4, the air'streamfollowing in the direction of the arrow A hitting the lip of the mouthand also -:the deflecting plate 9. ,Part of the air jet continues downthe pipe in the direction of the .arrow B and part goes out through themouth piece setting the deflecting plate 9 and the spring section 8 invibration. The frequency of the vibration of the spring 8 is establishedby its length, a the material of which it is composed and its weightdistribution governed by the .position of the adjustable slider 18 onthe spring. This slider may be set in the desired position as indicatedby calibration on the face of the spring or by the experience of theoperator. The vibration of the spring with the deflecting plate reachinto the mouth of the whistle in the region of the air jet will I causea warble in the note at a low frequency dependent upon thecharacteristics as set forth above. If it is desired to omit the warbleduring the blowing of the whistle, 'the end 17 of the spring may bepressed-down which raises the forward end of the spring and thedeflecting plate 9 away from the mouth whereupon a pure note will beobtained dependent upon the position of the plunger in the pipe. Tooperate the plunger 3 readily the rubber band 20 may be removed. Boththe plunger 3 andthe end of the spring 17 may be operated during theblowing of the whistleso that a note can be obtained varying in pitchand having a warble which may be omitted momentarily. This will supply acharacteristic bird note.

Bird notes are, in general, composed of a sound having a resonant pitchbut not particularly a pure pitch which may be varied over a frequencyrange together with a warbling of the note which, in some cases may bevaried by the bird. In the case of some bird calls, both a modu- :latedand un'modulated note is used. The embodiment of the invention which hasbeen described above produces means, for simulating these features ofthebird calls.

- However, at times it is desired to vary the pitch'or beat frequency ofthe warble while the call is being made. To "do. this, in Figure l theweight 18 would have to be moved ;pwithout damping thevibration of. thespring. This is more readily accomplished in the modifications shown inFigures 5 and 6 in which other advantageous features are also included.In this case the mouthpiece 1' is similar to the mouthpiece shown in-Figurel with the exception of a small projecting catchS"! at the bottomof the mouthpiece to en age an end 38 of the spring 39 which is .used totension the slide clamping collar 40- which'rnay be moved back-and forthalong the pipe 2 while playing. The collar 4%) may besquare in sectionwith an enlarged 1 base ll and a smaller head base 42, the collartapering at the sidesas indicated by the side sections 43, Figure 6,.The; spring 391 is a; leafspring with a sectiondd contacting the lowerface 45 of the pipe 2 and an overhang- "press against the forward end ofthe base 41.

' collar.

4 ing end 46 coming up against the rear edge 47 of the The lowerpart'ot' the 'spnn' is'iies 'agairist'the inner lower section 41 of thecollar and is bent over the forward end as indicated at 49. The springis so tensioned as to provide a space between the lower section 49 ofthe collar and the lower face of the tube. The upper section forming,the head 42 is provided with a longitudinal slot 50 in the center ofwhich are opposing knife edges 51 for gripping the spring 52 in an exactposition. The grip of the knife edges 51 act as a clamping means on thespring 52, and, therefore, as the ad justable collar 4i} is moved backand forth, the length of the spring from the position of theclampingknife edges to the deflecting plate end at 53, is increased anddecreased correspondingly. There'arend of the spring is held in place bya forced fit collar 54 fitting over the back end of the spring andclamping the end 55 of the spring which may have a pressed out boss 56pressing jfirmly into the clamping collar. The'clam'pingf'collar 54 maybe provided with an inwardly pr'ojecting'flan'ge 57 projecting againstthe plunger 58 with a suflicientjt'ol- 'eranc'e to allow it to bemoved'back and forth. The forward end of the plunger 58 has a slidingfit, as indicated at 59, on the inside of the tube with a shoulder, asindicated at 60,'for which the inwardly projecting flange or ,arm 57acts as a stop. In the innermost position'a' depression 61 in the top ofthe plunger 58 near its outer 'edge locks in place with a V-shaped latch62 formed'in .thespring section 55 beyondthe clamping end. When not inuse, therefore, the plunger may be pushed all the 'way in topermit thespring latch 62 to engage the depressiodfil. Similarly the collared mayalso be locked in position by advancing the collar until the springlatch 38Jengag'es' the projection 37 at the mouthpiece of the I whistle.When the collar is in this position the front edge 63 of 'the head 42comes upagainst the back of the deflecting plate 53 and acts as a restor support for the forward end'of the spring.

r A flange 64 may be pro- .vided at the sides of the spring to furnishfurther protection for it under all conditions.

In the operation of the modification shown in Figures 5 and 6 theplunger may be rnQVed forward and backvward as des1red. A calibration offrequency'or pitchas "indicating the pitch or frequency of the note.

indicated at65 may be provided on the walls of the tube corresponding tothe front edge of the plunger or piston In order .to change thefrequency of the warble, the

hco llar 40 may be moved back and forth while blowing. If the length ofthe section of the spring to the deflecting plate is mcreased the beatsof the warble will be (decreased and if the length is decreased thebeats of the warble will be increased per unit time.

Inorder to omit the warble it is necessary simplyto This will raise andtilt the spring upwards so that thedefiecting plate 53 will be drawnclear of the mouth in the tube. ,It will be noted from the description,above that the .;change of frequency of the warble and the omission orinclusion, of the warble is all accomplished without'inter- .rupting theplaying. The change of pitch or note will also be accomplished, orcourse, without stopping.

, The instrument shown, therefore, in Figures 5 and 6 can readily beused as a musical instrument in an orchestra, 'or otherwise, providingdesired characteristic changes as the playing of the orchestration mayrequire.

7 As a toy for the amusement of children, an ornamentation of a bird maybe applied to the whistle. This'form of invention is shown in Figures 7,8, 9, and 10. The

whistle in this case may be made longer than in the other forms ifdes1red to give the child blowing the whistle a better opportunity tolook at the bird. The bird, in

' Figure 7,'is mounted on the top side of the whistle with the feet 71preferably just forward of the mouth 72.

The air. passage 73 may, as in the other embodiments of the invention,direct the air jet into the mouth 72"and against the lip 74. Thedeflecting plate 75 may eittend into the mouth 72 as previouslyexplained and the'sp'ring 77 may extend upwards into the bird through anopening 76 in its bottom side just over the tube to the eye.

;The spring in this region may carry small eye plates ;78 extendingupward on either side which are seen through aligned eye openings 79 inthe bird. Thespring may also be bent forward in the section 80 extendingthrough the bird forming the lower beak. Fromjthis position the springis bent backwards as indicated at 81 through the length of the birdemerging from a slot 82' in the rear of the bird at which point areverse bend 82 may be formed in the spring to provide a clampingsection 83 which may be held in position by the side flanges 84extending up from the body of the whistle which may have internallyprojecting bosses 85 or be pressed against the sides of the spring inthe end of the section 83 to hold it in place.

At the end of the rear section 86 of the portion 81 of the spring, thespring may have a slightly upward bend providing a region which may bepressed down by the operator to raise the deflecting plate 75 clear ofthe mouth 72. In the operation of the device of Figures 7 to inclusive,the vibrating deflector plate and spring will cause the birds eyes tomove as well as the lower beak and provide an animation to the bird aswell as a warbling note. The operation of the modification of Figure 7may use a plunger or piston for varying the pitch of the note and italso may be provided with a slidable weight, as indicated in Figure 1 onthe spring to provide an adjustment of beat frequency of the spring.

In the modification shown in Figures 12 to iuclusive the device issimilar to the modification of Figure 7 except that the modification ofFigure 12 is intended to be molded of plastic principally by injectionmolding in two parts which are cemented together along their joiningedges. Figures 13 and 15 indicate this. As shown in these figures, thereis a right hand element 90 and a left hand element 91. The joining lineis at the bottom of the whistle in a shoulder as indicated at 92 at thecorner 3 of the tube or pipe passage 93. The section 91 comprisessubstantially the left half of the whistle with a top cover 94 extendingover the pipe 93 into a slot 95 in the wall 96 of the right hand half 90of the device.

The right hand half 90 on the other hand forms the 3 wall 97 of thepipe.

The whistle of Figure 12 is in the form of a log with a bird 98 whichmay simulate a Woodpecker standing on the log with its bill directedsomewhat over the mouth 99 of the whistle. the center as indicated bythe double line 100 and tr e vibrating spring 102 preferably has itsdeflecting plate 101 extending through a slot over the birds beak andprojecting into the top of the mouth 99. The groove 95 in which the topwall 94 of the pipe rests extends the whole length of the whistle andso, also, the shoulder 92. These are the lines which are firmly cementedtogether as well also as joining lines 100 on the bird. The mouth 99 isrecessed slightly into the side walls 96 and 96 of the tube as indicatedby the curves 103 and 104 (Figure 14). The air passage 106 through themouthpiece 105 is confined within the dotted lines as indicated (Figure14) so that the deflection plate 101 as it dips into the mouth will cut011 sharply the air passing through the air passage 106 impingingagainst the knife edge 107 and produce thereby a sharp cutoff of thenote which has the effect of making the warble very distinct.

It may also be noted in Figures 13 and 14 that the actual knife edge 107extends only between the inner surface of the side walls since the edge108 of the top wall is the full thickness all the way along the groove95. The side wall 96 of the whistle above the pipe may be provided withone or more locking'flanges 109 locking over the top wall 94 of thepipe. The spring 102 carrying the deflecting plate passes through themiddle of the bird which is hollow and is locked in place on the topwall of the pipe by means of an interlocking flange 110 extending fromthe side 90 in the wall section 96. This flange 110 engages a recess 111in the wall 96 and holds the spring base 112 firmly in place between thetop wall 94 of the pipe and the flange 110. An opening at the top of thebird not shown in the figures, but just over the bend 113 in the spring,permits the spring to be pressed down at that point to raise thedeflection plate 101 out of the mouth as in the other modifications whenthat is desired. A plunger 113 may be operated in and out of the end ofthe pipe.

In front of the clamping section there is provided a saliva block 114,which has deflecting walls extending diagonally downward and backwardfrom the center to 8 permit any saliva which may gather in the whistleto flow off through the opening 115 at the back of the birds feet. Theconstruction indicated in Figures 12 to 15 permits the whistle to bemolded of any suitable plastic material either by compression orinjection molding and 85 for various utilitarian purposes,

The joining line of the bird may be at 6 thereby facilitates the lowcost of manufacture with all the merits and attractiveness that thewhistle could have with more expensive and elaborate construction.

In the arrangement indicated in Figures 16 and 17 the whistle 116 may bemade of any suitable material, plastic or otherwise and differs from themodifications previously described chiefly in the use of a pair ofsprings 117 and 118 with deflecting plates 119 and 120 respectivelywhich do not dip into the mouth 121 of the whistle so that while thesprings will vibrate, the air jet in the mouth is not interrupted andtherefore no warble will be produced at the mouth. The springs 117 and118 may be mounted to the top wall 122 of the whistle and may havecuplike member 123, etc., attached to the springs at various points.These cuplike members are valves and cover and uncover holes 124 throughthe top wall 122 of the whistle. When air is blown through themouthpiece 125 and hits the deflecting plates 119 and 120, the springswill vibrate at different frequencies dependent upon their length andthe cups will cover and uncover the holes in the tube changing the pitcheffect and tone of the whistle in a regular and timed sequence. Thewhistle may be provided with a top cover 126 as a protection only forthe spring and may, therefore, permit air to escape which comes out ofthe tube 127.

In the modification shown in Figure 18 the whistle is made in the formto simulate a gun, 128. The gun is provided with a mouthpiece 129 in therear through which the whistle may be blown. On the top of the gun ismounted the vibratory spring 130 which has a deflecting plate 131dipping into the mouth 132. The spring 130 is retained by a slidablecollar 133 to which the trigger 134 is attached at the rear. Between thehandle 135 and the trigger 134 is a helical spring 136 wrapped aroundthe barrel 137 of the gun which acts, of course, as the pipe for thewhistle. As the trigger 134 is pulled against the helical spring thedeflecting plate 131 will enter the mouth 132 and create the warbleeffect when the whistle is blown. If the trigger is released the springwill be forced back to its original At the end of the gun is a smallprojecting boss 138 to prevent the collar 133 from coming free from thebarrel. A plunger 139 may also be provided to be moved in and out of thepipe and this plunger may be recessed throughout its length except atits ends so that it will be retained in the barrel 137 by the proectmgpm 140 on the inside of the pipe at the open end. The operation ofFigure 18 is quite readily understood. By workmg the trigger back andforth the warble may be created or eliminated at will. In thearrangement lndtcated in Figure 19 a double effect may be obtalnedincluding the creation of the warble at will simultapeously with thechange of the pitch of the note. For this purpose the gun 141 comprisesa bent tube 142 WhlCh acts as the handle of the gun. The tube 142 isformed in a U shape and is sufliciently flexible so that the centeropening 143 of the U can be made smaller and larger slmply by squeezingthe handle of the gun with the finger of the trigger 144. At the top ofthe gun there is mounted a spring 145 which is attached to the barrel146 and the gun in the section 147 of the spring. The spr ng extendsbackward to the handle and is provtded with a deflecting plate 148 whichmay engage the month 149 when the handle is squeezed. Air, then blownmto the mouthpiece 150, will vibrate the deflecting plate andsprmg 145and cause the plunger 151 in the open section 152 of the tube to move upand down. The plunger 151 is made to do this through the rod 153 whichis attached to the spring 145 between its clamping positron and thedeflecting plate. On steel spring, weight 154 may be magnetic tomaintain its position after each adjustment to adjust the vibratoryfrequency of the spring.

By blowing through the mouthpiece and causing the deflecting plate 148to engage the mouth 149 the spring will vibrate causing a warble and atthe same time a change in pitch. The deflecting plate may be movedalmost up to the mouth so that it vibrates without deflecting the airjet in the mouth as in the modification of Figures 16 and 17 in whichcase the spring will 0 vibrate to oscillate the plunger 151 and cause avariable pitch while if the spring remains in the position shown inFigure 19 a note of the same pitch will be produced.

Various forms and modifications of the invention have been illustratedin the drawings. These may be used as, for instance, toy- 7 andamusement devices, musical instruments, bird-walls and whistles, and, inlarge constructions, as adjuncts to organs and for other industrialpurposes. 'ln this respect the whistle may be operated both by anair-blast or by other means as by a steam blast. ln 'p'articular, wherea distinctive note or combinations of I notes are desired 'to 'beproduced, the device described in the present 'invention maysuccessfully be usedforthat purpose.
